[0032] Please refer to image 3 , the first embodiment of the present invention provides a liquid crystal display panel, the liquid crystal display panel includes a first substrate 20 and a second substrate 30 oppositely arranged, a liquid crystal layer 40 located between the first substrate 20 and the second substrate 30 and a frame Glue 41. The liquid crystal display panel is provided with an effective display area (AA area) and a non-effective display area located on the periphery of the effective display area. During the manufacturing process of the liquid crystal display panel, the sealant 41 is coated on the first substrate 20 or the second substrate 30 in a circular manner. , and located in the non-effective display area, liquid crystal is dripped in the range limited by the ring sealant 41, and then the first substrate 20 and the second substrate 30 are opposed to form a box, and the sealant 41 is cured, so that the liquid crystal layer 40 It is packaged in a closed s...

[0045] Please refer to Figure 5 , shows a schematic structural diagram of a liquid crystal display panel according to a second embodiment of the present invention. The difference from the above-mentioned first embodiment is that the through holes 310 are arranged in multiple rows in any horizontal side or vertical side, and the multiple rows of through holes 310 have specific layout rules.

[0046] Specifically, see Image 6 , the black matrix 31 includes a first area A1, a second area A2 and a third area A3, the second area A2 is set on the side of the first area A1 close to the effective display area, and the third area A3 is set on the side of the first area A1 away from the effective display area. One side of the display area, that is, the edge portion 311 of the black matrix 31 includes a ring-shaped second area A2 , a first area A1 and a third area A3 from inside to outside.

[0047] The thickness of the black matrix 31 in the third area A3 is greater than the thickne...

[0052] Please refer to Figure 9 , shows a schematic structural diagram of a liquid crystal display panel according to a third embodiment of the present invention. The difference from the above-mentioned first embodiment is that the liquid crystal display panel further includes an absorbing layer 36 located between the light diffusing layer 33 and the sealant 41, and the absorbing layer 36 includes dichroic dyes and liquid crystal molecules arranged in parallel to the axial direction. . Further, the first transparent insulating layer 22 is interposed between the absorption layer 36 and the metal circuit 21 , and the first alignment layer 23 covers the absorption layer 36 . Preferably, the width of the overlapping portion of the absorbing layer 36 and the sealant 41 is 0.5-0.95 times the width of the sealant 41 , and the width of the absorbing layer 36 is greater than or equal to the width of the sealant 41 .

[0053] When the liquid crystal display panel is produced and disp...

Abstract

The invention discloses a liquid crystal display panel and a liquid crystal display device. The liquid crystal display panel comprises a first substrate, a second substrate, a liquid crystal layer located between the first substrate and the second substrate and frame glue. A black matrix is arranged on the side, facing the liquid crystal layer, of the second substrate, the liquid crystal display panel further comprises a light diffusion layer, the light diffusion layer comprises polymer dispersed liquid crystals in free orientation, and the light diffusion layer is arranged between the first substrate and a frame glue or between the second substrate and the frame glue. The light diffusion layer scatters incident ultraviolet light, the irradiation range of the frame glue is enlarged, liquidcrystal pollution caused by incomplete curing of the frame glue is avoided, and edge light leakage is avoided.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a liquid crystal display panel and a liquid crystal display device. Background technique [0002] Liquid Crystal Display (LCD) has been widely used in all aspects of people's daily life. With the development of scientific and technological information products, LCD is developing towards the goal of light, thin and narrow frame. [0003] figure 1 It is a structural schematic diagram of a liquid crystal display panel in the prior art. In the manufacturing process of the liquid crystal display panel, the array substrate 11 is first coated with a sealant 14 and the liquid crystal 13 is dripped, and then the array substrate 11 and the color filter substrate 12 are Put them in a box, and heat or UV cure the sealant 14 . In the UV curing step, UV light is usually used to irradiate the sealant 14 from one side of the array substrate 11 to quickly cure it, so as to prevent the liquid c...
